`To all whom, it may concern: U

Be it known that I, LOUIS H. HEBERT, of StJohns, in the Province of Quebec7 inthe Dominion of Canada, have invented certain 5 neWand useful Improvements in Gar-Brakes;` and I do hereby declare the `following tobe a `full, clear, and exact description of the same. My invention relates to car-brakes of that description in which-the brake-power is deio rived directly from the motion-of the axles,

the brakeman merely having to start the Working mechanism.: I A

My improved brake is of such a description that it can be Worked from any point on the 15 top of a train of cars, or from the roof or floor ofthe brake-van. It consists, mainly, of `a friction-pulley journaled loose upon a spindle placed parallel to the axle, and "in a swingi'ramc consisting of arms pivoted below to a 2O bracket, which is secured to the bogie-fraine,

and held at the top by links pivoted to a lever Which is suitably `]'o`urnaled,.and having its long arm connected to the means of setting the brake.` A guide-pulley is also journaled 2 5 in the same swing-frame, parallel to the spin-` dle Acarryingthe friction-pulley, so thatwhen the lbrake is set the friction-pulley and guide. `pulley hold the .axle between them, `the guidepulley thus insuring `the contact of the axle 3o With the friction-pulley. A chain or rope is secured to the spindle upon which the friction` pulley is journaled, and when the latter is pressed against the axle it is rotatedand Winds up the chain or rope secured to the spindle,

` 3 5 thereby drawing a lever, which in turn draws the-` brake-lever, tightening the brake-blocks upon the wheels. When all the chain or rope has been Wound upon the spindle and the `.blocks are tight upon the Wheels, but the latis still receiving motion from the axle, but will now run `loose upon the spindle against the `pressure oi' a spiral spring, pressing the pul- `ley against a large iiange or` `collar upon the said spindle. The means of starting the mechanism consists of a lever pivoted on the iioor of the brake-van, being connected below to the vlever `controlling `the arm in which the friction pulley is journaled7 and provided ter still continue to rotate7 the friction-pulley` with a pawl or detent working in a rack. `The 5o lever controlling the arm in which the friction-pulley is journaled is further connected, by means of' a cord, to levers on the top of the car, coupled by a rod, said levers being also provided 'with pawl or detents, and with means 55 to connect with the adjacent cars.

Figure 1 is a top View of a car bogie or truck, showing the principal parts of the brake mechanism. Fig. 2 is a cross-section of the same on line c w. through the axle, showing the brakeimechanism inside elevation. Fig. 4 is an elevation of the same. Fig. 5 is a longitudinal section through the lever-arms carrying the spindle shown on an enlarged scale. Figli isalongitudinal section of a car having the `brake applied. Fig. 7 is an elevation of the end of contiguouscars, showing the connections.

A are the car-axles, and W are the Wheels. 7o B are the transverse beams of the bogie-frame. C is a bracket firmly secured to the beams B, and having its free end bent partly around the axle and bracket, being broad and formed into a long bearing (or two eyes) to receive the pin 75 d, by which the arms D are pivoted thereto. These arms D form a swing-frame of limited range, being held together at the top byapin, d', upon which are pivoted lthe links E, these being disposed in fork shape, andpivoted to 8O the lever H, close to the center or fulcrum upon thepin h,which is held in arms h', attached to l or forming part of the bracket G. The swingframe formed by the arms Dhas journaled in it a spindle, F, having near one end a large 8 5 iiange or collar7 f, terminating in a large neck or bearing, upon which thefriction-pulley F is journaled. This is pressed against the coll `lar f by a spiral spring7 f', placed upon the spindle, between two Washers, f2 f3, the outer 9o one of -which issecured and the pressure of the springregulated by a nut, f4. To the end of the spindle F projecting beyond the arm is fastened, so as to prevent `it from slipping, a cord or chain, F2, which is thence led over a 95 grooved pulley, d2, journaled upon the pin d, and secured to the lower end of the long arm ofthe lever I, which is centered upon the pin Fig. 3 is a cross-section 6o l upon which the friction-pulley is journaled, 65

h, and having its upper end or short arm connected by a rod or link to the lever K, pivoted on one of the cross-bars, M, which carry the brake .blocks or shoes N, and the lower short ,end connected by a rodto the other crossv bar, M', these being acted upon simultaneously and in opposite directions in the usual manner. In the frame formed by the arms D is also journaled,`a little below the frictionbowl F', a guide-pulley, G, this and the pulley F' being so disposed that whenthe swing-frame D is drawn .toward the axle the latter lies between the two pulleys, the guide-pulley G thus insuring the contact of the pulley F' with the axle A. An extra bar or. guard, D', is attached to the side of the'frame D D d d' to protect the overhanging ends of spindles. .The lever Hhas aiexure close to its center, at which the links E are pivoted, and terminates in a projection butting against the bracket C or beam B, and limiting the outward range of the swingframe D.

The action of this mechanism is this. ZVhenv pulley F' to rotate loose upon its' bearing.

should 'the axle still continue to rotate.

Should the part of the axle that is in contact with the pulleys F and G become worn and uneven, a split sleeve can be put upon the axle.

The following means are provided for setting the brake: A hand-lever, L, projecting into the interior of the brake-van, is pivoted under the iioor, having a detent or pawl, Z, pivoted to it above the floor, which meshes in the teeth of a rack, Z', secured to the floor of the van. The lower end or arm of said lever is connected to the long arm of the lever I-I by means of a link, Z2.

rIo enable the brakes to be set from the top of the cars, a lever, L', is pivoted at each end of the car and connected by a rod, R. A cord, O, is attached to the lever situated at the end of the car under which the wheels to be braked are located. This cord is led between two cordpulleys, Z3, placed in a bracket, l?, at about the. same height as the eye Z5, securing the cord to the lever, also over a cord-pulley, Z", below and connected to the lever H. The rod R may also? Abe pivoted to a lever, L2, placed overhead in part company would put on the brakes, as any deviation of the levers L' from the vertical or other normal position would pull the cords O, and by bringing the friction-bowl F' in contact with the axle would cause the chain F2 to be wound up or shortened and the brake-blocks tightened upon the wheels.

I claim as my inventionl. In a winding mechanism for an automatic car-brake, the combination, with an upright frame, D, containing a friction-pulley to bear upon the axle, of a supporting-frame, -O, havits upper end constructed and secured to the transfer beam or bolster B of the truck, and its lower, end extending thence downward and outward beneath the axle, whereby it is adapted to support the frame D in the required position outside of the wheel.

2. The swing-,frame consisting of the arms D D, pivoted below to the bracket C, and held above by the links E, j ournaled upon the pin cZ', the said frame having journaled in it a spindle, F, carrying a friction pulley, F', and a guide-pulley, G, so disposed that the axle comes in contact with the pulleys F and G when the frame is drawn toward the axle, the lower pivot, d, carrying-a grooved pulley, d2, and a guard IOO 4. In an automatic brake mechanism, the

combination of the swinging frame D, its friction-pulley adapted to encounter the axle, the

chain connected with saidpulley, the centrallypivoted lever I, the rod extending from said lever to the brake-lever K, and the jointed levers E H for controlling the position of the frame D.

5. The combination, in a brake mechanism, of the pulley-supporting frame D, pivoted to a supporting-arm on the truck, the link E, the leveroH, pivotally connected to the link E and to the truck, and provided at one end with an extension to serve as a stop, and at the opposite end with an eye, or its equivalent, adapted to receive the cord or operating device.

6. The combination of the axle A and bogieframe B, carrying a bracket, C, to the free end of which is pivoted the swing-frame D d d', which carries the guide-pulley G, and frictionbowl F', j ournaled frictionally upon the spindle F, having secured to -its end the end of a chain or cord, F2, led over avgrooved pulley, d2, to the end of the long arm of the lever I, which is linked to the lever K, pivoted on and working the brake-bars M M simultaneously and in opposite directions.

7. In combination with an automatic brake IIO 284.201 i p e mechanism, constructed substantially as lde`- scribed, with a controlling-lever, H, two handlevers, L', mounted upon opposite ends of the car, a rod connecting Said levers, anda cord p 5 or chain extending over suitable guides from one of said levers to the controlling-lever H fof the brake mechanism, whereby the brake mechanism may be operated from any point on the top of the car. p

8. `The combination of the automatic brake mechanism for controlling the lever H, a handlever, L,-mou1 ited Within theupper part of the car, and connecting` devices, substantially 'as described, extending from said lever, exter- 15 nally ofthe" car, to the lever H.
